Answer:
a) classical conditioning will not occur.
Step-by-step explanation:
If a UCS is presented after a CS -
after conditioning, Neutral Stimulus (NS) has become a Conditioned Stimulus (CS). If the conditioned stimulus regularly precedes the unconditioned stimulus, acquisition occurs. If the conditioned stimulus is presented by itself, extinction occurs. A pause after extinction yields a brief spontaneous recovery.
If you present the CS without the UCS-
If a CS is repeatedly presented without the UCS, extinction occurs. However, the response is not “unlearned” or “wiped out.” Spontaneous recovery can occur if the organism is allowed to rest after extinction and the CS is once again presented.
